PAsTEUnIzING-MiacmNE.

To all whom t may concern: l

Be it knownthat I, GUsTAv A. FISCHER, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, ful Improvement in Pasteurizing-Machines, of which the following is a specification, the principle of the invention being herein explained and the be'st mode in which I have4 contemplated applying that principle, so as to distinguish it from other inventions.

llhisA inventive conception relates, as regards its principal adaption, to a pasteurizing machine. The assembledstructure with its specific improving features lends itself however to alternative functions in a closely allied art.

Accordingly, the object of the invention,

while primarily to provide a feasible combiciple of my invention may be applied'.

Figure I is a vertical axial lsection of a machine in which the principle of my invention is incorporated, certain parts being seen in elevation. Fig. II is a part section, part end view on line II-II of Fig. I looking in the direction of the arrows. Fig. III is a section on line III- III 'of Fig. I looking in a similar direction.

The structural elements of my machine are, in logical order, an upright casing comprising two lateral supporting standards 1.

andend members 2. These. end members2 are of annular formation and moreover of angular cross-section to present tw'o substantial-ly horizontally extending annular danges 3 extending toward each other, as clearly seen in Fig. I. Theoutward portion of the interior annular surfaces of each of the Hanges 3 is fashioned with an annular depression 4 likewise bestrepresented in Fig. I. Surrounding the end members 2 is Specification of Letters Iatent.'

Appncation mea November 3o, 1912.

have invented a new and use- Patented Apr. 21, 1914. Serial No. 734,259.

an inclosing member 5 which is also kof angular cross-section so as to involve the two annular flanges 6 at opposite ends thereof. The member 5 is secured tothe member 2 through the medium of a suitable number of screws 7 In turn surrounding the member 5 and spaced a distance therefrom co1'- :responding with the extent of outward projection-of the flanges 6 is an arched hood 8.

It may be secured thereto in any ap ,proved manner, such as by soldering.v ii

The ood 8 is provided centrally with a stack 9. Underneath near the base ofthe standards 1 and extending substantially therebetween are a pair .of gas burners l0. The .construc- 7o tion should be understood to permit the substitution of a fire-box for these burners if desired or-if gas facilities are not at hanid.v

Disposed in a substantially horizontal position so as to extend through the openings in both of the members 2 vand project some distance beyond e'ach is a. pasteuri-zing cylinder proper 11. This cylinder is preferably of copper with open ends and 1s provided near each end with an iron collar 12 80V adapted to lie contiguous with the inwardly disposed annular surfaces of the flanges 3. In thislocat-ion with respect to the annular depressions 4 a common type of stuiing-box 13 is formed, whereby a water-tight relation 85 may be established between the members 2 and the surface of the cylinder 11 through the medium ofA` the usual packing glands 14 and packing `15 satisfactorily held in place throughthe medium of screw threaded studs 16 and nuts 17. Fixedly secured around opposite extremities of'the Ysurface of the cylinder 11 are'a pair of gears 18 adapted to mesh respectively with a pair' of driving pinions 19, in turn fixed through the medium of keys 20 to a driving shaft 21 connected with a source of power.

From so much of the description it will be readilyunderstood how a rotation 'on the part of the shaft 21 is transmitted to a 100 similar motion on the part of the cylinder 11. The direction of rotation of this cylinder is indicatedby arrows in Figs. II and III. It should be noted here that one end Of the cylinder 11 is flared as designated by 105' the reference numeral 22 in Fig. I, whereas the .opposite end tapers as designated by the numeral 23 in the same figure. As will now -be manifest by those familiar with this particular art, a closed jacket surrounding an y intermediary portion of the cylinder 11 is 'ity of perforations 27 extending substantially thereacross, and hand-hole 2 8 for inspection or cleansing purposes and finally a yconventional type of gage 29. Surrounding this water or steam jacket is an inclosing flue passageY establishing communication between the heating means below` and the stack 9.

A pipe 3()l extends 4through the inlet" end of the cylinder 11, which is in fact that end which is tapered, and is adapted to supply the Huid in uniform and regulated quantity to thebottom of the cylinder. Supported in any practical manner below the opposite flared end of the cylinder is a receiving funnel 31 adapted lto receive the now 6asteurized fluid. Fastened to and. exten ing outwardlyfrom each of the members 2 lati erally of their vertical planes is a bracket 32. These brackets are adapted to support a clamping member 33 which extends on an incline through the cylinder 11 as clearly represented in Fig. I. The relative position of this member 33 is furthermore on the same side with respect to the cylinder as the Y brackets 32 and this particular side of the cylinder is moreover the downwardly movj ing side as again indicated by the arrows in Figs. II and III. This clamping inem- 35 adjacent the funnel 31 while its upper end ber is curved at its lower end 34 which-is 35 is similarly bent downwardly adjacent the supply pipe 30. The precise position assumed by this member 33 interiorly of the cylinder is preferably inclined as already Y stated and speciically from the lower outlet end upwardly so as to barely intersect the horizontal plane of the axis of the cylinder.

*Along substantially that much of its length as Yis disposed within the cylinder 11, the member 33 is slotted'and it is within suchslot` that any suitable type of wiper 36 is intended to be removably secured through the instrumentality of the transverse openings 37 and thumb screws 38. 'Ihe'proxiinity of the clamping member 33 with respect to the lower quadrant of thecylinder surface is such that the wiper' secured to it may have suiiiciently strong Contact.

The operation o' my lmachine may be thus described: Assuming the water within the jacket to have become sufficiently heated either through the means of the firebox or gas burner outside, or the steam pipe 26 inside thereof; and rotation to have b een. imparted to the cylinder in the direction shown, thefluid to be pasteurized may be supplied preferably by means of a pump through the pipe 30. Thereupon the latter.

is carried upwardly upon the interior properly heated surface of the cylinder. On account o they adhesive tendency of most of the fluids which are subjected to the pasteurizing operation, such iiuid willbe carried around as a film or sheet beyond the top of the cylinder-and halt` again as far or until it is wiped o' by the wiper 36 at its 'specific point of Contact therewith. The slope of the wiping contrivance in the meantime insures the downward travel of the. liquid in the direction of thefunnel 31. Especial cognizance should be taken of the fact that my arrangement of the several parts compels the iiuidunder treatment to travel ay nearly maximum' extent upon the interior surface of the cylinder.

` Having now. fullyfy described my invention, what I *claim and desire to secure by Letters Patent is: i
